Driving along and without warning drive seems to have quit. No matter what gear no go. On Jack stands all wheels and drive lines rotate freely. No noise, no disconnect. Could this be an electrical issue? Fuse (F102=TCM)? I seen this topic before but never resolved. Thx. One note, for about a day before the shifting seemed to be stiffer, shifting at lower rpm and gas mileage went down? Hmm?
